The lithium ion batteries (LIB) are the most perspective source of energy for portable devices. The main advantages of lithium ion batteries compared with the former ones are high operating voltage and high energy density. However, the transport application requires further development of materials for lithium ion batteries with high current compatibility and stability. A novel anode carbon material was prepared through the carbonization of apricot stone. The material has been characterized using XRD, SEM, specific surface area measurements (BET) and tested as a potential anode for lithium ion batteries. It was shown that the material had a low crystallinity and presumably considered as disordered carbon. The material is thermally and electrochemical stable and showed exceptional steady capacity and pronounced electrochemical stability as electrode in half-cell tests versus lithium electrode. The cycling behavior of the carbonized apricot stone system is similar to those of other carbon materials [14]. During the initial cycle, it shows higher initial irreversibility which is related to protective film formation on the electrode surface. However, the system shows high reversibility closer to 100% cycling efficiency during the subsequent cycles which extended up to 200 cycles. Novel anode material exhibited outstanding cycleability at high charge-discharge current rates. Surface modification procedures applied to increase performance stability of carbon anode materials [15,16] may be used to increase the carbonized apricot stone cycleability and rate capability. Application of the smaller sized powder will be useful to increase specific capacity and high rate cycling performance of the electrochemical system with novel carbon material. The present work has revealed that carbonized apricot stone is a promising anode material for lithium ion batteries in large-scale application.
